A plurality of “shared” folder-corresponding storage areas shared between a plurality of electronic music devices are provided, and the music contents in each storage area are further divided and stored under a plurality of types of folders.

[Server folder structure and electronic music device display]
In one embodiment of the present invention, when the electronic music devices 11 to 1n access the server computer 2, the music information file (music content) can be immediately received from the storage device of the server computer 2. FIG. 3 schematically shows a folder structure of music contents in the storage device of the server computer according to one embodiment of the present invention.

  As shown in FIG. 3, the music content that can be used by the plurality of electronic music apparatuses 11 to 1n is abbreviated as a “music content root” folder (“root” folder) in a storage device provided in the server computer 2. In the second level immediately below the music content root, “My Document 1”, which can be individually used by the users of the “paid content” folder and the plurality (n) of electronic music apparatuses 11 to 1n, respectively. ”,“ My Document 2 ”, etc., a plurality (j: n or more) of“ My Documents ”folders, and a plurality of (n) users of the electronic music apparatuses 11 to 1n having a plurality of sharing electronic relationships. A plurality (k) of “shared” folders such as “shared 1”, “shared 2”,. Each “shared” folder is a folder shared by users of a plurality of electronic music apparatuses belonging to one group, and this group is appropriately assigned to each group at the time of user registration as described later. Or participate at any time after user registration.

  Further, in the third level under the “paid content” folder, “SMF”, “ringtone”, “karaoke”, “electronic organ”, “electronic piano”, “electronic score”, “ A plurality of types of folders such as “sound source waveform”, “accompaniment style”, “tone parameter”,. Similar folders (not shown) are also placed in folders such as other My Document folders and shared folders in the same hierarchy as the “paid content” folder.

  Under these type-specific folders, a plurality of music information files belonging to the type of music information are stored as a fourth layer (file storage layer). For example, a standard music information file in the SMF (Standard MIDI File) format is stored in the “SMF” folder, various ringing melody music information is stored in the “ringtone” folder, and karaoke is stored in the “karaoke” folder. Music information is stored, and music information dedicated to the electronic organ and the electronic piano is stored in the “electronic organ” and “electronic piano” folders.

  In one embodiment of the present invention, when a user accesses a server computer from an electronic music device, the server computer displays an accessible folder on the display of the electronic music device in response. FIG. 4 shows an example of a display display screen of the electronic music apparatus in such a case.

  When a certain user accesses the content providing server 2 from a certain electronic music apparatus 1, the display 1S of the electronic music apparatus 1 includes, for example, a “paid content” folder in the second hierarchy folder shown in FIG. Then, icons of “My Documents” and “Shared” folders, which are My Document folders and shared folders that can be used by the user in the electronic music apparatus 1, are displayed in a list. Here, when the icons of the “paid content” folder and the “My Documents” folder are sequentially “opened” (double-clicked), for example, as shown in FIG. 4, the “paid content” folder and the “My Documents” folder are displayed. A “paid content” window and a “My Documents” window that represent the arranged third hierarchy folders in a list are displayed on the display 1S.

  In one embodiment of the present invention, the music information file (music content) is copied from the “paid content” folder to the “My Documents” folder by operating the folder icon displayed on the display screen of the electronic music device. The music information file can be purchased. FIG. 5 shows an example of a display display screen of the electronic music apparatus in such a case.

  On the display screen of FIG. 4, for example, when the “SMF” folder icon in the “paid content” window and the “SMF” folder icon in the “My Documents” folder are operated (double-clicked), as shown in FIG. A “paid content-SMF” window and a “my document-SMF” window are displayed on the display 1S. In the illustrated example, icons or characters representing a number of SMF music information files stored in the “SMF” folder of “paid content” are displayed in a list in the “paid content-SMF” window (FIG. 5). On the other hand, the “My Document-SMF” window is blank, and no music information file is stored in the “SMF” folder of the My Document. Is displayed. You may display a summary of the title of each content and the lyrics, composer, artist, and the like.

  Here, as shown in the figure, an icon representing a desired content (for example, “FFFF.mid”) is designated from the “paid content-SMF” window and dragged and dropped into the “My Document-SMF” window. When the “copy” operation is performed, the music information file is copied from the “paid content” folder to the “my document” folder, and thus the music information file can be purchased. At this time, billing processing is also performed.

[Overall processing]
6 and 7 are flowcharts showing the overall processing of the music content storage system according to the embodiment of the present invention. This whole process is called “music content providing process”, the processing part on the electronic music apparatus side is called “terminal side music content providing process” or “terminal side whole process”, and the processing part on the server computer side is “ It is referred to as “server-side music content provision processing” or “server-side overall processing”.

  On the electronic music apparatus 1 side, after the apparatus is turned on and the terminal-side music content provision processing program is started (step E1), first, the electronic music apparatus ID of the electronic music apparatus 1 and the electronic music apparatus 1 are set. The user ID and password of the user being used are input (step E2), and the input electronic music apparatus ID, user ID and password are transmitted to the server computer 2.

  Here, the electronic music apparatus ID is a unique identifier given to each electronic music apparatus 1 in advance, and is embedded in the ROM 1B or the like at the time of manufacture so as to be automatically input. May be embedded in the RAM 1C. For example, when the electronic music device 1 is purchased and the user is registered with the manufacturer, the electronic music device ID is automatically input when the electronic music device ID is sent from the manufacturer. You may keep it. The electronic music apparatus ID preferably includes a model identifier corresponding to the model or function of the electronic music apparatus 1.

  Also, it is preferable to set the user ID and password in advance. For example, the user accesses the server computer 2 from the electronic music device (electronic musical instrument or PC) in advance, and performs user registration for the music content storage service to acquire a user ID and password. Once the user ID and password are entered, the entry may be omitted for the second and subsequent accesses.

  On the other hand, the server computer 2 performs processing such as user authentication. That is, user authentication is performed based on the electronic music device ID, the user ID, and the password transmitted from the electronic music device 1, and when the authentication is completed, the “My Document” folder and “Share” corresponding to the electronic music device 1 are completed. Access to the folder is permitted (step S1). Each folder corresponding to the electronic music apparatus 1 is registered (assigned) on the server computer 2 side as an available folder at the time of the above-described user registration. Next, the display data of the access-permitted folder and the pay folder are transmitted to the electronic music apparatus 1 (step S2).

  In response to this, the electronic music apparatus 1 displays on the display apparatus 1S a window screen relating to an available folder permitted to access the electronic music apparatus 1 based on the display data transmitted from the server computer 2 ( Step E3) Since the folder operation by the user becomes possible, a folder operation detection process for detecting the folder operation by the user is performed (step E4). When the folder operation is detected in the folder operation detection process, a “folder operation” command is transmitted to the server computer 2 (E5).

  When the server computer 2 receives the “folder operation” command, the server computer 2 performs processing corresponding to the command, and transmits display data obtained as a result of the processing to the electronic music apparatus 1 (step S3). Folder operations include “open”, “close”, “create new”, “delete”, “copy”, and so on. For example, in the case of an “open” operation, the server computer 2 transmits a list of folders or files one level below the folder in which the “open” operation has been performed to the electronic music apparatus 1 as display data.

  The folder accessible by the electronic music apparatus 1 is a folder suitable for the model or function of the electronic music apparatus 1 from the type-specific folder in the “My Documents” folder using the model identifier included in the electronic music apparatus ID. Configured to select. For example, if an electronic music device capable of displaying a score can be displayed as an “electronic score” folder, but an electronic music device capable of not displaying a score is not displayed as an “electronic score” folder. , Users don't get confused. Similarly, the “shared” folder and the “paid content” folder can be configured to select a type-specific folder to be provided to the electronic music apparatus 1 using the model identifier. Note that only “open” and “close” are possible for a folder below the paid folder, and “new creation” cannot be performed.

  The electronic music apparatus 1 displays the processing result corresponding to the “folder operation” command based on the transmitted display data (FIG. 7: step E6). For example, for the “open” operation of the “paid content” and “my document” folders on the left side of FIG. 4, as shown on the right side of the same figure, the “paid content” and “my document” windows are one level below each folder. List the folders. For an “open” operation of a folder (eg, “SMF”) in the lowest folder hierarchy (third hierarchy in FIG. 3), the music information file stored in the folder is displayed.

  When the display corresponding to the “folder operation” command (E6) is made, or when the folder operation is not detected by the folder operation detection process (E4 → NO), the music information file is displayed on the display device 1S of the electronic music device 1. May be displayed and the file operation by the user may be possible. Next, a file operation detection process for detecting the file operation by the user is performed (step E7). When a file operation is detected in the file operation detection process, a “file operation” command is transmitted to the server computer 2 (E8).

  When the server computer 2 receives the “file operation” command, the server computer 2 performs processing corresponding to the command, and transmits display data obtained as a result of the processing to the electronic music apparatus 1 (FIG. 7: step S4). File operations include “new creation”, “deletion”, “copy”,... For example, in the case of a “new creation” operation, a new file is created and its icon is transmitted as display data to the electronic music apparatus. For files in the paid folder, only “copy” is possible, and “new creation” is not possible. Then, after performing “other processing” (step S5), the process returns to a standby state in which an instruction from the electronic music apparatus 1 such as access or command is received.

  On the other hand, the electronic music apparatus 1 displays the processing result corresponding to the “file operation” command based on the transmitted display data (step E9). After this display or when a file operation is not detected in the file operation detection process (E7 → NO), “other process” is performed thereafter. If no power off is instructed, folder operation detection process (E4) Returning to “Folder operation” detection (E4) to “Other processing” (E10) until the power-off is instructed. When the power-off is instructed, this terminal-side music content providing process is terminated.

  “Other processing” includes “playback / editing” and “file transmission / reception” processing, “content purchase” processing, “content search” processing, “co-operation” processing, and the like between the electronic music apparatus 1 and the server computer 2. There are a process performed in cooperation and a process performed independently by the server computer 2 such as a “change my document capacity” process.

  A single user can access the server computer 2 from a plurality of electronic music apparatuses 1a and 1b. In this case, it is only necessary to input the same user ID and password, but the electronic music devices 1a and 1b used by the user are visible according to the model identifier included in the electronic music device ID as described above. The folder by type changes.

["Play / Edit" and "File Send / Receive" processing]
In one embodiment of the present invention, a music information file (music content) stored in a server computer can be used for playback and editing on an electronic music device, and the edited music information file is again sent to the server computer. Can be saved. FIG. 8 is a flowchart showing “playback / editing” (terminal = electronic music apparatus = side) and “file transmission / reception” (server side) processing that enables such playback / editing and storage.

  Based on the display data sent from the server computer 2 in response to the “folder operation” and “file operation” commands described above, a list of music information files under the “My Documents” or “Shared” folder is stored in the electronic music apparatus 1. It is displayed on the display device 1S. Here, in the case where there is a music information file that the user wants to play back or edit, when the user designates and selects the file (step E21) and performs an operation for requesting the file transmission, the electronic music apparatus 1 displays “file A “transmission request” is transmitted to the server computer 1 (step E22).

  In response to the “file transmission request” from the electronic music apparatus 1, the server computer 1 transmits the requested music information file to the electronic music apparatus 1 (step S21). On the other hand, the electronic music apparatus 1 receives the file and stores it in the RAM 1C (step E23), and at the same time, selects a file operation selection screen (for example, “play” or “edit”) on how to use (operate) the file (for example, , “Play”, “Edit”, and “Cancel” buttons are displayed on the display 1S, and first, a playback operation detection process for detecting whether or not “Play” of the file is selected. (Step E24).

  When an operation for selecting “play” of a file is detected in the playback operation detection process, the music information file stored in the RAM 1C is played on the electronic music apparatus 1 (step E25). For example, a corresponding musical tone is generated from the musical tone generators 1H, 1J, and 1T based on the file, or a corresponding musical score or the like is displayed on the display 1S.

  After the music information file playback process (E25) or when the "playback" operation is not detected in the playback operation detection process (E24-> NO), it is detected whether "edit" of the file is selected. Editing operation detection processing is performed (step E26). When the “edit” selection operation is detected in the editing operation detection process, the music information file stored in the RAM 1C becomes editable and can be edited by the user's operation (step E27).

  When the user finishes the editing operation and gives an instruction to end editing, the electronic music apparatus 1 displays a screen for allowing the user to select whether or not to save the edited music information file (referred to as “file after editing”). A save operation detection process is performed to detect whether or not “Save” is selected for the edited file (step E28). When selection of “save” is detected in the save operation detection process, the electronic music apparatus 1 transmits the edited file to the server computer 2 (step E29).

  Then, after the edited file is transmitted (E29), the selection of “edit” is not detected in the editing operation detection process (E26 → NO), or the selection of “save” is not detected in the storage operation detection process. If this is the case (E28 → NO), the music information file stored in the RAM 1C is forcibly deleted (step E30), and then the process returns to the terminal-side overall process (FIG. 7: E11).

  On the other hand, when receiving the edited file, the server computer 2 performs a process of storing (newly writing or rewriting) the received edited file in the corresponding “My Document” or “Shared” folder (step S1). After that, the process returns to the server-side overall process ("Return" in FIG. 7).

["Content purchase" processing]
In one embodiment of the present invention, the music information file (music content) stored in the “paid content” folder of the server computer is simply copied to the “My Documents” folder corresponding to the electronic music device. With a simple operation, a desired music information file can be purchased. FIG. 9 is a flowchart showing a “content purchase” process that enables such a file purchase.

  On the display device 1S of the electronic music apparatus 1, based on the display data sent from the server computer 2 in response to the aforementioned “folder operation” and “file operation” commands, for example, as shown on the left side of FIG. A list of music information files under the “paid content” folder can be displayed in a window, and a folder under “My Documents” can also be displayed in a window as shown on the right side of FIG.

  Here, when there is a music information file that the user wants to purchase in “paid content”, the user of the electronic music apparatus 1 designates and selects the icon of the file displayed in the “paid content” window. (Step E41) When an operation (drag and drop) for copying this icon in the “My Documents” window is performed (Step E42), the electronic music device 1 displays the operation content for the file together with the “content purchase instruction” in the server. It transmits to the computer 1 (step E43), and then returns to the terminal side overall processing (FIG. 7).

  The server computer 2 receives the “content purchase instruction” from the electronic music apparatus 1 and performs a charging process corresponding to the purchased music information file for the user who has given the “content purchase instruction” (step S41). In this billing process, the user may be able to select the usage period of the purchased music information file (content), and the charge may be changed according to the usage period. For example, a range such as use only once, use for a certain period (such as “one month”), permanent use, etc. may be determined, and different charges may be set according to the range. In this case, the purchased file whose usage period is limited is deleted from the My Documents folder after the usage period has elapsed. Further, it is preferable that the charge for each content is presented to the user in advance when a list is displayed as shown on the left side of FIG. 5 or when an icon is selected in step E41.

  Next, the server computer 2 performs a server usage fee reduction process in accordance with the content purchase (step S42). In other words, the purchase of paid content (music information file in the “paid content” folder) reduces the server usage fee. In this case, the amount may be reduced forever or may be reduced for a certain period from the time of purchase.

  After the server usage fee reduction process, the purchased file in the “paid content” folder is copied based on the operation content of the electronic music apparatus 1 for the music information file for which “content purchase instruction” has been issued, and the user (Step S43). Thereafter, the process returns to the server-side overall process (FIG. 7).

["My document capacity change" processing]
In one embodiment of the present invention, the storage capacity of the “My Documents” folder can be automatically changed in the server computer in accordance with the amount of information of the music information file stored in the “My Documents” folder. FIG. 10 is a flowchart showing such “My Document Capacity Change” processing for changing the capacity of the “My Document” folder. This processing flow is activated every time a file is processed in the “My Documents” folder of the server computer 2.

  First, the server computer 2 performs the file processing such as new writing / rewriting (S22) or copying (S43) of the music information file for each “My Document” folder, so that the storage capacity of the “My Document” folder is increased. An excess capacity determination process is performed to determine whether or not the currently set upper limit of storage capacity (simply referred to as “set storage capacity”) has been exceeded (step S51).

  If it is determined in the excess capacity determination process that the current setting storage capacity is exceeded, the setting storage capacity set in the “My Documents” folder is increased (step S51), and the server usage fee is increased according to the increased setting storage capacity. The usage fee increase processing for increasing the amount is performed (step S53).

  Next, after [the usage fee increase process (S53) or when it is determined that the current storage capacity is not exceeded in the capacity excess determination process (S51 → NO)], the music information file is rewritten for each “My Documents” folder. The file capacity such as (S22) or deletion (for example, based on the “delete” operation) is performed, so that the storage capacity of the “My Documents” folder is set to a predetermined value from the currently set storage capacity (upper limit value). As described above, the capacity decrease determination process is performed to determine whether or not the value is lower (step S54).

  If it is determined in the capacity reduction determination process (S54) that the current set storage capacity has fallen below the predetermined value, the storage capacity set in the “My Documents” folder is reduced (step S55), and the reduced set storage capacity is set. Accordingly, a usage fee reduction process for reducing the server usage fee is performed (step S56). Then, after the usage fee reduction process (S56) and in the capacity reduction determination process, if it is not determined that the detected storage capacity is less than the predetermined setting capacity (S54 → NO), the server side overall process Return to FIG.

Server (“My Documents” folder) usage fee is determined in advance according to the capacity of several stages, for example, how much the setting storage capacity is (0MB ~) up to 5MB, how much (5MB ~) up to 10MB, etc. It has been. Therefore, when a new set storage capacity that is increased or decreased from the current set storage capacity is newly determined (S52, S55), the server usage fee is also increased or decreased according to the increase or decrease in the set storage capacity (S53, S56). In addition, when increasing / decreasing the server usage fee, the user may be inquired about whether the increase / decrease in the server usage fee is OK. The server usage fee is also increased or decreased for the “shared” folder in the same manner as described above (the usage fee burden for each user is determined by a separate contract).

["Content Search" processing]
In one embodiment of the present invention, when a search condition is set on the electronic music apparatus side, a music information file (content) satisfying the search condition is extracted on the server computer side, and the extraction result is notified to the electronic music apparatus side. it can. FIG. 11 is a flowchart showing a “content search” process for performing such a file search.

  In this processing flow, first, on the electronic music apparatus 1 side, a search range is designated by a content type (SMF, ringing melody song,...) Or a folder type (paid content, my document,. Step E61). Next, in order to enable a more accurate search from a viewpoint different from the folder structure, for example, a search phrase (performance) is input (step E62). Then, a search command is transmitted from the electronic music apparatus 1 to the server computer 2 together with these content type, folder type and phrase (step E63).

  Upon receiving the search command, the server computer 2 searches the content in the range specified by the received content type or folder type for content that matches or is similar to the input phrase, and extracts the corresponding content ( Step S61). For example, if the content type = “electronic score” and the folder type = “paid content & my document” are specified as search targets, the electronic score file included in the “paid content” folder and the “my document” folder The content that matches the input phrase is extracted from the electronic score file included in.

  Next, the server computer 2 creates a list of extracted contents and transmits it as display data (step S62), and then returns to the server-side overall process (FIG. 7). On the electronic music apparatus 1 side, after the content list is displayed on the display 1S based on the received display data (step E64), the process returns to the server side overall process (FIG. 7).

  If the extracted content is in the “paid content” folder, it can be purchased, and if it is in the “My Documents” folder or the “shared” folder, it can be used.

  In this content search process, it is preferable to extract not exactly the same, but also those that are different in tone from the input phrase, or those that are partially different in sound. Thereby, even a user who is ambiguous or a user who is not good at playing a phrase can find the target content.

["Collaboration" processing]
In one embodiment of the present invention, music information files (contents) in a “shared” folder of a server computer can be edited together among a plurality of electronic music apparatuses. FIG. 12 and FIG. 13 are flowcharts showing the “cooperation” process that enables music information editing between such a plurality of electronic music apparatuses.

  In this processing flow, first, a certain music information file in the “shared” folder is selected by a certain electronic music apparatus (referred to as “electronic music apparatus 1a”) (step E71), and transmission of the selected file is performed. The request starts from the server computer 2 (step E72). On the other hand, since the requested file is transmitted from the server computer 2 (step S71), the electronic music apparatus 1a stores the file received from the server computer 2 in the RAM 1C (step E73).

  Prior to editing the received music information file, it is determined whether there is a track being edited by another user (step E74). When it is determined that there is a track being edited by another user, Tracks other than the track being edited are made editable (step E75), and when it is determined that there is no track being edited by another user (without restrictions on the track to be edited), the edit stage ( Proceed to steps E76 to E81).

  When proceeding to the editing stage, the electronic music apparatus 1 first performs an edit instruction operation detection process for detecting which one of the “edit” and “cancel” buttons displayed on the display 1S is operated (step E76). In this editing instruction operation detection process, when it is detected that the start of editing is instructed by operating the “edit” button, the electronic music apparatus 1a enters the editing mode. First, the user designates a track to be edited in the music information file. Then, an editability determination process for determining whether or not the track is an editable track is performed (step E77).

  When the editable track determination process determines that the track is an editable track, the electronic music apparatus 1a notifies the server computer 2 that the track is “editing” (FIG. 13: step E78). . In the electronic music apparatus 1a, the track can be edited by the user's hand (step E79). On the other hand, the server computer 2 that receives the communication from the electronic music apparatus 1a uses the electronic music apparatus 1b ("1b" represents a part other than the electronic music apparatus 1a) used by another user who is editing the same file. The user is notified that the predetermined track of the file is being edited by the user of the electronic music apparatus 1a (FIG. 13: step S72).

  In the electronic music apparatus 1a, when the user finishes the editing operation and instructs the end of the editing, an end instruction screen for allowing the user to select whether or not to “save” the music information file (the edited file) in which the track has been edited is displayed. An end operation detection process is performed to detect whether or not “Save” is selected for the edited file displayed on the display 1S (step E80). When the selection of “save” is detected in the end operation detection process, the electronic music apparatus 1a transmits a message to the effect that the editing has been completed to the server computer 2 together with the edited file (step E81). If no selection is detected, the server computer 2 is notified of the cancellation of the “editing” (E78) that was previously communicated (step E82).

  Then, after the editing end comment and the edited file are transmitted (E81), when the selection of “edit” is not detected in the editing instruction operation detection process (E76 → NO), the track is not editable in the editability determination process. Is determined (E77 → NO) or after the cancellation of editing is notified (E82), the music information file stored in the RAM 1C is forcibly deleted (step E83), and then the terminal side overall processing (FIG. 7: Return to E11).

  On the other hand, when the server computer 2 receives a notification (E82) for canceling "editing", the server computer 2 notifies the electronic music device 1b used by another user to that effect (step S73). . In addition, when the editing end comment and the edited file (E81) are received, the received edited file is stored in the “shared” folder (rewrite update), and the electronic music device 1b of another user is also processed. On the other hand, the end of editing of the electronic music apparatus 1a is notified and the edited file (updated file) is transmitted (step S74). Thereafter, the process returns to the server-side overall process (FIG. 7). In the above-described rewrite update process and the transmission process to the other electronic music apparatus 1b, it is preferable to rewrite and transmit only the edited track data.

  On the other hand, the other electronic music apparatus 1b receives the music information file (E81, S74) that has been edited by the electronic music apparatus 1a (FIG. 12: step E73), and updates the file on the RAM 1C to the latest one.
